Got two calls on the same day. Recorded message promoting Air Canada/Amer Airlines vacations at Cancun and Disney World. Listened to the WHOLE message but only options were to accept or decline their offer. How can I be placed on Do Not Call List?

This is third in a month from the same group - but they use a different phone number each time. Recorded message promoting Air Canada/Amer Airlines vacations at Cancun and Disney World. Listened to the WHOLE message but only options permitted were to accept or decline their offer. How can I be placed on Do Not Call List?
